If the underlying app implements a /x/dbug/state endpoint in +on-peek, dbug will now use that for %state evaluation. Falls back to the vase provided by +on-save if the peek fails. This allows apps and (perhaps more usefully) wrapper agents to provide customized vases to /lib/dbug. Updates /lib/shoe to make use of this, properly prepending the wrapped app's vase to shoe's own, instead of including it as-is.
